the numbers you see all make sense. the FPS module is unfortunately not part of the opencv codebase, but assuming it "just works" --
if you wait for 25 millis in waitKey() you get 1000 / 25 = 40 FPS, minus some for image drawing, so 38.06 looks quite exact.
to play at (about) 24fps, try adjust the wait time to 42 millis, so you get 1000 / 41 = 24.3. (and again, with a bit of additional time spent for drawing, it should get quiite exact)
